I would use Excel and make one axis your FDR with different pinions, and your y axis different diameters.
This, of course, would be very useful for anyone running foam tires, where you can true the diameter that you want. I'll try and whip one up and attach it.
Twisted, what kind of chassis are you running and what size spur?
